The women rescued included 27 Mexicans and 19 foreigners, Mexico City prosecutors said in a statement.

Forty people were detained after a raid at the Cadillac table-dance club in the country's capital over the weekend, prosecutors said. Fourteen of them face charges of human trafficking for sexual exploitation, the statement said.

While an estimated 10,000 women were victims of human trafficking in Mexico's capital in 2010, there were only 40 investigations of the crime and three convictions in the city that year, according to a report from the organization.
